Swap on loopback could deadlock with whatever file system, not only FUSE.

The correct and safe way to use swap with FUSE is using the fuseblk fstype 
and a swap file on the FUSE file system (so it's exactly the same as one 
would do with an in-kernel file system). This completely avoids the usage 
of user space during swapping. This is in use for over a year with ntfs-3g, 
e.g. by Knoppix and Mr Klaus Knopper wrote only positive things to me so 
far.
